Description

Principles of matrix grading for the immobilization of high-level wastes are treated. Conclusion about the possibility of actinide fraction separation and its introduction in matrixes in its own right from fission products is made. It is suggested to establish values of storage period according to leaching rate of radionuclides and matrix materials from matrixes. Standard procedure for the leaching using crushed materials is to be regulated for this. Two criterions for the comparison of matrix materials are proposed

Abstract (Russian)

Рассмотрены принципы подбора матриц для включения высокоактивных отходов. Сделан вывод о необходимости выделения актиноидной фракции и ее включения в матрицы отдельно от продуктов деления. Предложено установить значения продолжительности хранения в зависимости от скорости выщелачивания из матриц радионуклидов и матричных материалов. Для этого необходимо регламентировать стандартную методику выщелачивания с использованием измельченных материалов. Предложены два критерия для сравнения матричных материалов
